CHATSWORTH, Calif. (KTLA) -- Authorities are trying to find a man who is posing as a police officer with a fake badge and preying on young girls in the Chatsworth area.

The suspect tried to arrest a 14-year-old girl and molested another girl after telling her he needed to put a tracking device in her bra, police said.

The incidents took place near Lawrence Middle School.

The suspect, in his 20s, is described as Hispanic or Asian, about 5 feet 5 inches tall with brown eyes and brown hair.

In one case he was wearing a Superman shirt and in another he was wearing a shirt "with a logo on it," an LAPD detective told KTLA.

Police say citizens should always look for more than just a badge and should ask to see the officer's picture identification.

A Los Angeles Police Department badge is blue in color and has the officer's name and rank along with their picture.

Anyone with more information about the man was asked to call detectives at (818) 832-0609.

If you take this story in conjunction with the story of the guy on the motorcycle arrested for recording a police officer, then you start to see a very, very serious problem with our law enforcement system.
